CARTON ENVELOP OR PAPER BOX.

SPECIFICATION forming part of Letters Patent No. 587,836, dated August10, 1897.

Application filed July 31, 1896. Serial No. 601,290. (No model.)

To all whom it may concern:

Be it known that I, KARL LANZ, a subject of the German Emperor, residingat Augsburg, in the Kingdom of Bavaria, Germany, have invented certainnew and useful Improvements in Paper Boxes or Carton Envelops, of whichthe following is a specification.

In the drawings, Figure 1 is a section of the box, showing thefastening-tongues. Fig. 2 is a front view. Fig. 3 shows the top section;Fig. l, the bottom section. Fig. 5 shows a paper band embodying featuresof my invention.

The drawings show in Fig. 1 the lateral section of a card box. Thebottom or and the top m are shaped to form a box and the two parts areheld together by tongues and slits. The cover or top m is formed with atongue q of reduced width, which engages a slit 8 in the end of the box,passing through the same, and to further secure the parts the tongue ghas a slit (1, with which engages a tongue 2, cut out of the body of thebox and as shown in Figs. 1, 2, and 3.

In Fig. 5 is shown a paper band having the tongue q and slit g at oneend and the slits s and z at the opposite, and in the folding of theband the ends engage each other, as above.

Instead of making the top and bottom separate, as shown in Figs. -1 to4, the box may be made with flaps to engage each other across the topand bottom of the box, one flap having the tongue q and slit q and theother flap having the slit 5 and tongue 2.

I claim- A paper box and the like and means for securing the partstogether comprising a tongue, an adjacent part having a slit to receivethe tongue, a slit in the tongue, and a tongue formed in said adjacentpart adapted to en gage the slit in the tongue of the first part, bothof the said tongues being carried through to the inside of the box, thepart m securing a firm hold by being pushed through the main slit tobring its slit beneath the supplemental tongue, substantially asdescribed.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

KARL LANZ.
